The plate-tectonic concepts that developed rapidly in the late l960s made possible the understanding of island arcs. Before that time, mobilistic concepts evolved slowly, hindered, particularly in the United States, by an obstructionist geoscience establishment. The volcanic belts of island arcs form about 100 km above subducting plates.
